When I try to import my 1099-B from my WeBull, I don't see any detail in 1099-B after connect to my account. after I hit import the 1099-B disappear. any thoughts on why?

after I connect my WeBull there are 3 forms (1099-B, 1099-DIV & 1099-INT), the other two are fine but there is not detail under 1099-B, then after I import I can only see the other two imported. WeBull said the data is normal and I didn't meet this issue when importing my wife's 1099-B
